COP COVER.

Application filed March 16, 1922/ Serial No. 544,095.

To all whom it may concern:

Be it known that I, JOHN H. Voor, a cit-- izen of the United States, residing at Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Cop Covers, of which the following is a specification.

My invention relates to means for maintaining in proper condition the copped thread employed in knitting operations; and it consists in the novel device hereinafter fully described in connection with the accompanying drawing and specifically defined in the subjoined claim.

It is well known in the knitting art that proper and uniform conditioning of the fed thread greatly facilitates the knitting operation and improves the resulting product; and that this is particularly important in the use of certain materials such as artificial silk now frequently employed. The main practical requirement is for the maintenance of the fed thread in a determined moderately moistened condition, in order roduct may be satisfactorily and uniform y knitted throughout at all times; and as a means to this end it is recognized to be important that the wound bobbins or cops be kept in a properly moist atmosphere prior to lacing them upon the machine as needed. have found however that during necessary intermissions in the knitting, the exterior thread particularly of the exposed cop is so materially aifected by the action of the surrounding atmosphere as to decidedly aifect the character of the resultant product when knitting is resumed after such intermissions; and the purpose of my simple but practically important invention is to satisfactorily avoid this wasteful failure to insure uniformdesired texture.

The drawing shows my new device in partly sectional elevation and in connection with a cop of ordinary form to which it is applied as indicated.

My invention provides in a simple manner for keeping the thread upon the machine mounted cop, during more 01' less rolonged intermissions in knitting, in a like atmosphere to that inwhich it is kept prior to being applied to the machine; and to this end it consists in providing a shaped cop cover, integrally formed of a suitable -absorbent material such as heavy felt, with a conical cop-enclosing skirt portion 10, depending from an integral top-closure portion 11 adapted to rest centrally upon the projecting cop spindle 12, as shown, and extending around the base 13 of the cop, so as to provide a limited air-space 14 between the surface of the Wound thread and the shaped cop cover at any used or unused stage of the cop; the purpose and effect of said cover being to carry a moistening liquid absorbed thereby, so that the air in said restricted annular space 14 around the cop thread will be properly moisture-laden by evaporation from thewetted cover to maintain thethread in normal condition during any required interval of non-use. This cover may be very satisfactorily made of felt material blocked to desired shape and sizin as indicated, or of equivalent material and ormation.

What I claim is: p

As a new article of manufacture, a shaped cop cover of absorbent fabric having a conical cop-enclosing skirt portion depending from an integrally formed top-closure portion; the latter being adapted to be centrally supported upon the cop spindle, and the bottom of said skirt portion being adapted to looselyencircle the cop base, substantially as set forth.

In testimony whereof I aflix m signature.
